The importance of ammonia transmitter in the breeding industry

 With the development of the aquaculture industry to standardization, intensification, and modernization, the breeding environment has become a prominent problem. The waste from the breeding farm not only has a negative impact on the livestock and poultry itself, but also poses a serious threat to the surrounding environment. Therefore, it is necessary for poultry farms to effectively monitor harmful gas components in the environment.

Studies have shown that livestock and poultry farming is a major emitter of ammonia, and after the ammonia reacts with the oxidation products of sulfur dioxide and nitrogen oxides, ammonium nitrate and ammonium sulfate are generated, which are important sources of PM2.5. According to reports, ammonia gas comes from the feces and urine excreted by livestock and poultry. If it is discharged at will, it will be very harmful to the environment. Therefore, it must be recycled and reused. The biomass in the feces and urine is consumed as much as possible. Reduce environmental risks.

Harmful gases such as ammonia, hydrogen sulfide, carbon dioxide, etc. produced in farms affect the health of livestock and poultry themselves, but also have a significant impact on the human environment, especially ammonia. Therefore, the hazards and pollution of ammonia in livestock and poultry production should receive further attention, establish systematic and scientific livestock and poultry house ammonia standard detection technology, carry out monitoring of ammonia emissions in livestock and poultry houses, and grasp the ammonia pollution in livestock and poultry houses. Status, providing important technical support for energy conservation, emission reduction and efficient production.

The large-scale aquaculture industry has continuously increased the stocking density, which has brought about an increase in ammonia emissions per unit area. If you smell ammonia but it is not glaring or pungent, its concentration is about 15-20ppm; when you feel pungent and tearing, its concentration is about 30-40ppm; when you feel difficult to breathe, you can’t open your eyes At this time, its concentration can reach more than 70 ppm. After ammonia enters the blood, it reduces the amount of dissolved oxygen in the blood and reduces the resistance of livestock and poultry. Long-term exposure to an ammonia concentration of 10-15 mg/kg will significantly reduce the animal's stress resistance.

The aqueous solution of ammonia gas is alkaline and irritating to mucous membranes, which can cause tearing and burning of the eyes, inflammation of the cornea and conjunctiva, and visual disturbances. High concentrations of ammonia can cause symptoms such as cough, bronchitis, pulmonary edema, bleeding, and suffocation. In addition, ammonia gas can raise the pH value of the mucus in the respiratory tract, make the cilia lose their activity, and cannot discharge the filtered harmful substances out of the body, increasing the susceptibility to airborne diseases. When the ammonia in the pig house reached 65 ppm, the animals began to develop respiratory diseases, and at 75 ppm, allergic rhinitis appeared, and the incidence of both increased sharply as the ammonia concentration increased.

The high concentration of intestinal ammonia can stimulate the intestinal mucosa and accelerate its growth and metabolism. This will increase the need for oxygen and energy, while the excess ammonia in the intestine is absorbed into the blood, and finally converted into amino acids and excreted waste. The detoxification process of these ammonia is a highly energy-consuming process, and the energy used by animals for growth and production is correspondingly reduced, which affects growth performance. When the environmental ammonia is 50ppm, the animal's weight gain rate drops by 12%, and when it is 80ppm, it drops by 30%.

At present, the ammonia content in livestock and poultry houses ranges from 10 to 30 ppm, and as much as 100 ppm. The national pollution-free breeding standard stipulates that the ammonia concentration in the pig house is 25mg/m3. Therefore, how to reduce ammonia emissions has become a key control point for the profitability of the aquaculture industry. Therefore, an ammonia sensor is now introduced for intelligent breeding, which uses systematization to control the breeding environment and create the most suitable growth environment.
